Aurora Forecast Tonight in Saskatoon

Aurora season in Saskatoon runs from September to April.

Tonight's Forecast

Moderate

How we calculate the aurora score

Moderate

We combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Saskatoon (region: high_latitude).

With current Kp 5.0 (location needs ≥ 3) and 66% cloud cover, aurora may be visible at Saskatoon from a dark spot, once your eyes have adjusted.

Unlikely 0-19

Score 0–19. Conditions strongly limit aurora visibility.

Low 20-44

Score 20–44. A faint aurora is possible only under perfect conditions.

Moderate 45-64

Score 45–64. Aurora may be visible to alert observers in dark, clear skies.

High 65-84

Score 65–84. A good chance of a visible aurora display.

Very High 85-100

Score 85–100. Excellent odds — plan to be outside tonight.

Moderate chance tonight. Aurora may be visible from a dark spot if the sky stays clear.

Aurora Score 57 /100

Aurora activity may be favorable near Saskatoon, but cloud cover could make the Northern Lights difficult or impossible to see.

With current Kp 5.0 (location needs ≥ 3) and 66% cloud cover, aurora may be visible at Saskatoon from a dark spot, once your eyes have adjusted.

🧭

Direction to Look

Overhead or north

Min Kp 3 Lat 52.1°

This is a high-latitude location, so aurora may appear overhead or toward the northern sky.

Recommendation

Cloud cover is the main problem tonight. Wait for breaks in the clouds before going out.

Why this forecast?

There is a moderate chance of visible aurora tonight. Some conditions are favorable, but clouds, moonlight or geomagnetic activity may still limit visibility.

✓

Geomagnetic activity 5.0 / 3

Geomagnetic activity (Kp index)

Strong for this location

Kp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Saskatoon needs Kp ≥ 3.

Below threshold

Kp is below the minimum needed at this latitude.

Near threshold

Kp is close to the minimum needed — a faint aurora may appear low on the horizon.

Enough for this location

Kp meets the threshold for visible aurora here.

Strong for this location

Kp is comfortably above the local threshold.

Geomagnetic storm

Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.

Strong for this location

Expected Kp 5.0 is comfortably above the 3 Saskatoon usually needs, so the oval should reach well past this latitude if the sky cooperates.

•

Cloud cover 43%

Cloud cover

Partly cloudy

Average cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.

Clear skies

Up to 25% cloud — excellent visibility.

Partly cloudy

25–50% cloud — aurora may peek through gaps.

Cloudy

50–85% cloud — most of the sky is blocked.

Overcast

Over 85% cloud — aurora effectively hidden.

Partly cloudy

Some clouds are expected, but aurora may still be visible through clear gaps.

✓

Darkness astronomical

Sky darkness

Astronomical darkness

Aurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.

No dark window

Sun stays above 6° below horizon all night — no aurora-friendly darkness.

Civil twilight

Sun 6–12° below horizon — too bright for faint aurora.

Nautical twilight

Sun 12–18° below horizon — sky is dark but not fully astronomical.

Astronomical darkness

Sun more than 18° below the horizon — fully dark sky.

Astronomical darkness

The sky reaches full astronomical darkness tonight — the sun more than 18° below the horizon, dark enough for even a faint aurora.

Moonlight 77%

Moon illumination

Bright moon

A bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.

Dark moon

Less than 25% illuminated — minimal interference.

Moderate moonlight

25–75% illuminated — faint aurora may be washed out.

Bright moon

Over 75% illuminated — only strong displays will be visible.

Bright moon

Moon is 77% illuminated — expect washed-out faint aurora.

Aurora oval probability 1%

Aurora oval probability (OVATION)

Low

NOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.

Low

Less than 5% probability — aurora unlikely to reach this location.

Moderate

5–20% probability — aurora possible.

Elevated

20–40% probability — aurora likely if skies are clear.

High

Over 40% probability — aurora very likely overhead.

Low

The aurora oval probability is low for this location tonight.

Aurora zone Good zone

Aurora zone

Good zone

How favourable Saskatoon's latitude is for aurora viewing in general — independent of tonight's conditions.

Low zone

Lower latitude — aurora is rare and requires a major storm.

Fair zone

Mid-latitude — aurora visible only during moderate-to-strong storms.

Good zone

High-latitude region — aurora is visible on most active nights.

Excellent zone

Directly under the auroral oval — aurora is a regular occurrence.

Good zone

Saskatoon is in a good aurora region, where aurora is possible during moderate geomagnetic activity.

Frequently Asked Questions

Can you see the Northern Lights in Saskatoon tonight?

Some nights. At 59.8° geomagnetic latitude Saskatoon sits outside the quiet oval, so it takes moderate activity — Kp 3 and above — to bring the ring within reach. Cloud and darkness decide the rest.

What Kp index is needed to see the Northern Lights in Saskatoon?

Kp 3. The oval widens about 2° toward the equator with each step up the scale, and Saskatoon is roughly 6° outside its quiet edge — which is why a single extra point changes what you see here.

What are the best months to see the Northern Lights in Saskatoon?

September to April, with November to February giving the most hours of real darkness. The March and September equinoxes carry a statistical tilt toward higher activity — a shift in the odds, not a promise for any one night.

Where is the best place to see the Northern Lights in Saskatoon?

Saskatoon is large enough that its own sky-glow is the main obstacle, so plan on leaving it. Head out away from the lit side until the glow is behind you, and find an open view toward the north — a lake shore, a ridge, anywhere the horizon is not built up. Let your eyes adjust for 20–30 minutes once you are there, and keep the phone screen off.
